Systemic Lupus Erythematosus (SLE) is a multisystem autoimmune disease with an estimated incidence of 5-50 cases per 100,000 people. Despite advances in therapy, there is still significant mortality and morbidity associated with this disease. There have been no clearly defined treatment goals in SLE, hindering the development of treat to target approaches and evaluation of new therapies. Although remission is aimed for, it rarely occurs. A more achievable clinical state and treatment goal of low disease activity has been described recently and a preliminary single centre validation study has demonstrated its association with improved outcomes. This endpoint is termed Lupus Low Disease Activity State (LLDAS).
